यदि (y=(r+8)x+(r-4)) मूल बिंदु से गुजरती है, तो इसकी ढाल क्या होगी?
If (y=(r+8)x+(r-4)) passes through the origin, what will be its slope?
Explanation opens after your attempt
C. (12)
Concept
To pass through the origin, (r-4=0). Thus (r=4) and the slope is (12).
Why this answer is correct
The correct answer is C. (12). To pass through the origin, (r-4=0). Thus (r=4) and the slope is (12).
Exam Tip
मूल बिंदु से गुजरने के लिए (r-4=0) होगा। इसलिए (r=4) और ढाल (12) है।
